Uh, yes, TTL would apply to USB tethering (if that is what they are looking for). TTL is part of IPv4 (it's called hop limit in IPv6) which is a couple levels up from the physical layer (in your case USB) in the OSI model. I mean, whether you use USB, or Ethernet, or WiFi, you're still just shuffling packets around.

Well that sucks. I suppose the best thing to do is have the tethering apps not decrement the TTL, though I have no idea if any of them support that.

Again, it's not the tethering app that does it, it's the TCP stack. It's likely quite possible for a custom Android ROM to implement this workaround, but I would be surprised if you could accomplish that with an iPhone.
